The arc of a circle element and the arc of an ellipse element begin at the 3 o’clock point on the associated radius and progress towards the 9 o’clock point. The starting point and direction of the arc are affected by the user space transform in the same manner as the geometry of the element.
For an example of how the starting point and direction of an arc (for an ellipse) are affected by a user space transform, see the cx topic.
